Example, how to chain normal functions together with the await keyword in JS/TS to collect data first and execute the request later

chain-functions.js

const functions = {
  data: {},
  // we are using normal style function definitons for having a reference to this...
  select: function (select) {
    console.log('select', select)
    this.data.select = select
    return this
  },
  eq: function (eq) {
    console.log('eq', eq)
    this.data.eq = eq
    return this
  },
  limit: function (limit) {
    console.log('limit', limit)
    this.data.limit = limit
    return this
  },
  filter: function (filter) {
    console.log('filter', filter)
    this.data.filter = filter
    return this
  },
  then: async function (onfullfilled, onrejected) {
    console.log('awaiting via then!')
    // do some async stuff here
    try {
      console.log('doing a DB calll here')
      onfullfilled({ data: 'your data here' })
    } catch (err) {
      console.error('got remote error', err.message)
      onrejected(err)
    }
  },
}

const from = (name) => {
  const localFuncs = Object.assign({ data: { name } }, functions)

  console.log('returned local funcs', localFuncs)
  return localFuncs
}

async function main() {
  const stuff = await from('my dbName')
    .select('my column name')
    .eq('some data')
    .limit(1)
  console.log(stuff)
}

main()
